Insulation system for technical installations

An insulation system (1) for pipes, containers, ventilation ducts and like installation parts which have an outer surface temperature which periodically is below the dew point of the ambient air, said insulation system comprising a thermally insulating layer and (5), a layer of a vapour barrier (2) arranged on one side of the thermally insulating layer, and a layer of hygroscopic material (3), said layers being circumferentially arranged in such a manner that the insulation system (1), starting from the outside, comprises said vapour barrier (2),

• said layer of hygroscopic material (3), and said thermally insulating layer (5), the layer of hygroscopic material (3) being arranged between the layer of the vapour barrier (2) and the thermally insulating layer (5), said hygroscopic material (3) being at least partially connected with the vapour barrier (2), and
• the combination of the vapour barrier (2) and the hygroscopic material (3) being connected with the thermally insulating layer (5) in such a manner that the hygroscopic material (3) partially makes contact with the thermally insulating layer (5), and with said layer of hygroscopic material (3) being arranged so as not to make contact with the outer surface of the installation part that receives said insulation system.
